Study on the performance of accessory microbial fuel cell (MFC) integrated to the constructed wetlands (CWs) for deep wastewater treatment

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 318, P. 100358 - 100358

Published: April 1, 2024

Deep nitrogen removal is difficult due to inefficient organic carbon sources in tail water from sewage treatment facilities. Microbial fuel cell integrated with constructed wetlands (MFC-CWs) filled high density polyethylene (HDPE) as the biocarriers were for deep denitrification of water, and was compared MFC CW. The influences electrode gap hydraulic retention time (HRT) on well electricity generation performance investigated. It found that appropriate extension might enhance chemical oxygen demand (COD) removal, MFC-CW got highest at 25 cm. Extending HRT promoted denitrification, resulting an initial increase followed by a subsequent decrease power performance. maximum attained 1.95 mW/m2 2 d. microbial abundances upper cathode systems higher, growth metabolisms microorganisms enhanced MFC-CWs. Saccharimonadales SBR1031 dominant genera, which removal. results provide reference study synchronous HDPE bio-fillers.

This paper aims to comprehensively explore the performance and influencing factors of constructed wetland–microbial fuel cell (CW-MFC) system when treating brine with different concentrations. The main objective is determine how salinity levels affect operation treatment efficiency CW-MFC system. research results show that Bruguiera gymnorrhiza exhibits strong salt tolerance can be used as a wetland plant for closed-circuit planted plants has best performance, chemical oxygen demand (COD) removal rate 84.8%, total nitrogen (TN) 68.12%, chloride ion (Cl−) 29.96%. maximum power density 64.79% higher than without plants. generation first increases then decreases increase in salinity, while internal resistance keeps decreasing. When 2%, effect best, an average output voltage 617.3 ± 25.7 mV 45.83 mW/m2. rates COD TN are inhibited phosphorus (TP) not significantly affected. microbial community grows well under stress, but its structure different. 1%, optimal distance between electrodes 10 cm. Considering pollutant hydraulic retention time 3 days, considering 2 days. provides important value improving brine.

Enhanced biomass production and bioelectricity generation in microalgae culture medium using electrode pairings

E3S Web of Conferences, Journal Year: 2025, Volume and Issue: 603, P. 03007 - 03007

Published: Jan. 1, 2025

Microalgae-based biofuel production offers promising avenues for sustainable energy generation. However, optimizing microalgae culture conditions enhanced biomass and bioelectricity generation remains challenging. This study addresses this problem by investigating the efficacy of different electrode pairings immersed in a medium. Two pairs, Al-Fe Cu-Zn were evaluated their impact on growth production. The optimum concentration obtained was 1.204 g/L electrodes with lipid content 15.1% 0.36V. results demonstrated that induced high culture, facilitating biodiesel Conversely, Cu paired Zn promoted elevated 0.95V. research sheds light potential tailored to optimize dual-purpose biofuels production, contributing advancement technologies. It recommended, among others, further exploration diverse within cultured medium could unveil additional effective strategies
